APPARATUS AND METHOD OF IMPROVING VOLUMETRIC EFFICIENCY IN AN INTERNAL COMBUSTION ENGINE |
摘要 |
Volumetric efficiency is reduced in a premixed gaseous fuel engine compared to a premixed liquid fuel engine. An improved method for operating an internal combustion engine and improving volumetric efficiency comprises storing a gaseous fuel in a liquid state; determining a load on the internal combustion engine as a function of engine operating conditions; determining a target temperature for the gaseous fuel that reduces the likelihood of pre-ignition and knock as a function of the load; and controlling the amount of heat transferred to the gaseous fuel to convert it to one of a gas state and a supercritical state, such that the gaseous fuel is introduced into the internal combustion engine at the target temperature. |

1. A method of operating an internal combustion engine and improving volumetric efficiency, said method comprising:
storing a gaseous fuel in a liquid state; determining a load on said internal combustion engine as a function of engine operating conditions; determining a target temperature for said gaseous fuel that reduces the likelihood of pre-ignition and knock as a function of said load; and controlling the amount of heat transferred to said gaseous fuel to convert it to one of a gas state and a supercritical state, whereby said gaseous fuel is introduced into said internal combustion engine at said target temperature. |
